Whey Protein and Lactose


Does whey protein concentrate have lactose?


Lactose is a sugar present in milk (including cows milk) that is broken down by the enzyme lactase found in the small intestine. All naturally occurring sugar in whey protein is lactose. Whey Protein Concentrate contains approximately 2g of lactose per 30g serving.


The small intestine—the organ where most food digestion and nutrient absorption take place—produces an enzyme called lactase. Lactase breaks down lactose into two simpler forms of sugar: glucose and galactose. The body then absorbs these simpler sugars into the bloodstream for energy. Lactose intolerance occurs when there is a deficiency of lactase enzyme in the small intestine needed to digest the lactose. The undigested lactose passes into the colon where natural bacteria ferment the lactose and produce acids and gas. If you are  lactose intolerant, you may experience symptoms after consuming lactose including bloating, abdominal cramps or possibly diarrhoea.


Most people with lactose intolerance can handle small amounts of lactose, such as a glass of milk which contains 8-10 grams of lactose. A single serving of whey protein contains less than 2 grams of lactose. Consult your doctor of health professional before consuming if you are lactose intolerant. If you are uncertain try a half serving first and wait to see if you have any symptoms. 


Non Dairy Protein Alternative


Although Whey Protein is the number one choice for most people, Rice Protein is an alternative protein source suitable for persons with diagnosed lactose intolerance.


What is the best protein powder for me?


Whey Protein and Rice protein contain similar amounts of protein per serving (80%) although the amino acid profile is different. Both types of protein can assist you with your protein goals to either develop lean muscle mass or weight loss.
